Appiicmon sied March 1, 1910. seriai No. 546,650.

'Be it known that I, KARL MAIER, a citizen of f the German Empire, residing at Stuttgart, in the Kingdom of `Wurttemberg, Empire oi Germany, have invented certain new and yuseful Improvements in Change- Making Machines; and I do hereby declare the following. to be a full, clear, and exact ofthe invention, such as will enable others killed in the art to which it appertains to make and use the same.

rIhis invention relates to a combined regsuch as the like.

The improved machine belongs to the, type in which cashreceived and sales keys are providedand in which in addition to the automatic "-.registering of the various amounts, the difference is mechanically issued, so that the salesman himself has noth. ing to do lvvith-themoney. Such machines have not yet come into practical use, as the constructions designed therefor are much too complicated to be adopted, and consei quently in the long run do not Work with certainty, as, on account of the numerous vmoving parts employed, they easily' get out of order, moreV particularly when largely used. NOW by this improved machine these disadvantages are entirely avoided, and it is 'particularly characterized by its verysimple construction.

The invention Will now be more particularly described in connection with the accompanying Adrawings, which giveexamles of some-forms of construction.

Figure l is a front view in perspective of the machine as a whole; Fig. 2,a plan view of a portion of the recording band; Fig. 3., a sectional side View of the machine; and Fig.' 4, a diagram explaining the action of the working parts; Fig. 5 lis. a plan view ofthe Working parts; Fig. 6', a `front view of one half of them; Fig. 7, a side view on an enlarged scale of Fig. 6; Fig. 8, a sideview of another form of construction.

`The registering and change giving machine 1 in accordance with this invent-ion, isprovided in the ordinary vvay With a series of` keys 2 for the dollars received, and a similar series of keys 3 for the cents vre ceived, a series of keys 4 'is also' provided for the amounts of the sales in dollars, and

'levers 2 turn Yto all, and-have -pin 22 provided, for instance, with a a similar series ffor vthe amount of ,the sales in cents.

The ejection, that is to say the delivery of change is eiected by means of an ejector 6, which encounters the uppermost coins 7 which are piled upsorted in a coinframe 8, and lare constantly drawn upward by a spring. The ejected coins 7 then fall into l a single common hoppeiyor nn11el:9,-be neath the outlet of which a scoop 10 may be held (Figs. 1 and 3). `Now in order to register n the payments, thev sales and che change given, an indicating device 115101? known construction is provided which prints the amounts automatically side byvside in a visible manner on a strip' 12 byv means of a printing device 16. At the same time the sums received can then be seen and: the. amounts checked through a Window 13', and' the amounts of theV sales through a window 14,'vand the change given through a. window 15(Fig,1).

IThe keys, as is usual with coin issuing apwith bars 17, the numberof teeth and arrangement of Whichcorresponds, with the value of the key in question. These bars 17 encounter levers 18 and cause these toiturnr in one direction. v"According to this invention the levers for the dollars are formed as double-armed levers, rby -ine'ans 'of' which they may be keys 2 encountering the part 18 of the leviers andthe keys 4 the part 19. The cents levers" y are only Vsingle and are moved in the same direction by the cash-received keys and also by.` gv'sales keys. Of course thedollars arrangement might be employed for the lcents and vice versa,- the cents arrangement `ior-A thedollars, but it isnot preferable to do -so because it is rarely in the caseov the dollars 9 that amounts of one hundred have to -be calcul'ated,y while With cen'ts' this is mostly the 'Each oi the levers 1S, 19 and 20 'is connected by a link 21 with a bell crank lever 33, one such bell cranklever and one such connecting mechanism being providedfor each of the ejectors 6. All these bellpcrank.

a slo't 25 in. ivhich a 'guide roilgr engages, which pin is carried by the l'mi 21 (Figs. 3 and ,7). In a normal position the.v

paratus, are provided at their 'lower endsv n o u turned 1n two directions, .the

looselyon a-shaft 24 common l' pins 22 of the dollars side are all uncoupled or out of action of the spindle 37 end lie at the outer end,that;is to say at the front end u lof 'the elbow levers 23. :Now if one'of the keys 2 be depressed, the pin 22 moved by it isnthereby displaced'ingthe slot 25 into the. other end position and coupled with the ejectingl spindle A37. In order to. automativ cally retainthe pin 22 in each of the e'nd positions, a lever 261v is provided which is' loosely 'pivo'ted on the spindle l2 4: and which I islunder the action of a jspringf27` and is provided with notches 28, in which the pin y22`rests, these notches 22 vbeing of such a form, that a' slight pressure suffices to transfer the vpin 22y from one end .position to another. L On the centssideonthe contrary,l the pins 22,1ie intheir normal position at i-f the inner-end of the slots 25v and are coupled 2O witl1 .the ejecting spindlev 37. VIfVhen the sums-received andsalesl'keys are depress ed,l .-'so many voithese pms areuncoupled thatl only the excess famountrecelved remams'ad- 25 z levers ,`29,and30 ,with the ejectors 6, so that when.' the elbow ylevers turn .the.' `,e'jectors justed and. capable of beingv ejected;

This missing.y dollar is' th`en adjusted from thmeents sale keys 5. VFor the casewhenthe .amontofthe'sale 'contains no' cents', a 00 #'salekey, is provided, Which key on the one hand -`throws-"g"out of .action all cents feouplings,.an d von'` the other hand encounters With an elector 42 on the dollars side, in

order to adjust the;v arrangement for the Amissing dollar` so @that the klatter ,can be ejected. The 00 key 40 in the penny device vis' actuated when only single dollars are calculated. This key '40 actuates the rocking arm 41 (Fig. 5) and? the latter engages the one dollar ejector.

The'acti'on of the improved machine is as olloWsz-Say Van amount of $20 has been received, While'the saleprice is only7 $17 .60,

and thus'the purchaser must receive $2.40

change, the salesman then first depresses the $20 received key 2, "whereby the: -yokes 1'8 land 19 by'rneans of the-transfer member hereinbefore explained,v setfready for operati'on'all'the ejectors 16 -on the dollars Side,

In the same manner the cents sales key 5 is depressed, which throws' out of- `action lthe ejector making iupV the. amount 'of-(50"cents, that iste say,` the completion up to' 100, sojthat''onlyI 40cents are given in changetThe handle-veri 31 is now .putover and la'cordinfclgly. $2.40 drop into, the.' hopper" 1 9.5;' Should'f the-amount of the; sale .only- 17 offthe Sales jkeys, .which would eii'ectthis operation' (Fig. 8).
